how to do a compression t
what i do is take the coil wire off the distributor but leave it on the coil and put the distributor end somewhere where it won't arc. Then i just put the compression tester ina cylinder and crank the motor over 3 times. I've never done anything about the fuel system. I've done it a few times and my car always starts. It's definetely rich at first but it cleans itself out quick

pull the relay , washing your wall down with gas does not do well with tryin tosimulate what actually goes on in there ,and the coil too . crack the throttle wide open , and have all the plugs out . also do it while its still warm , (ring end gaps), do a dry one and then one with a squirt or oil to see if there is a huge difference in the quality of your ring seal. good luck
